In 1918, she opened a business on the
Kurfürstendamm in Berlin; it became one of the most popular studios in the city. Partly as a result of her marriage to the journalist
Rudolf Leonhard in the early 1920s, she extended her clientele to celebrities such as playwright
Walter Hasenclever, novelist
Gerhart Hauptmann and actors and actresses including
Tilla Durieux,
Asta Nielsen and
Emil Jannings. This group extended to include dancers, music-hall stars and fine artists:
Anna Pavlova,
Mistinguett, Lil Dagover,
Renée Sintenis,
Max Liebermann and
Xenia Boguslawskaja. Other clients included representatives of the old aristocracy, diplomats, politicians and bankers. Boxers (and nudes thereof) were a notable group in which she specialised, including Erich Brandl, Hermann Herse,
Max Schmeling, Ensor Fiermonte. Such was her renown that she became known simply as
Die Reiss. While on a trip to Italy in 1929, she was invited to photograph
Benito Mussolini. In addition, she contributed to the journals and magazines of the day including
Die Dame,
Berliner Illustrierte Zeitung,
Der Weltspiegel,
Querschnit and
Koralle. ==Move to Paris==
